If the problem still persists I would suggest you to check this guide: https://www.jotform.com/help/364-Why-I-am-not-Receiving-Email-Notifications
Also, you could try setting up your custom sender email address using the SMTP feature that will allow you to have more control over the sender info, here's the guide that will help you with that: https://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form
